Brake fluid subject gaskets to extreme conditions. High temperatures occur when brakes are applied frequently, causing heat to build up. If a gasket cannot resist this heat, it may degrade or fail, leading to leaks. Chemical resistance is equally important because brake fluids contain additives that can corrode or break down gasket materials. If the gasket fails chemically, it can compromise the entire braking system.
Chemical resistance refers to the ability of materials to withstand exposure to chemicals without degrading. In the context of brake fluids, common chemicals include hydroscopic (water-absorbing) substances and additives that enhance performance.
Gasket failure often results from high temperatures and harsh chemicals causing material breakdown. When temperatures exceed the gasket’s tolerance, it may harden or lose elasticity, leading to cracks. If the gasket or seal is made from materials like rubber or silicone that lack adequate chemical resistance, contact with brake fluid can cause swelling or tear, further risking leaks and brake failure.
Specific conditions that contribute to gasket issues include prolonged high temperatures, frequent hard braking, and the use of substandard gasket materials. For example, in heavy-duty vehicles, continuous usage in harsh conditions can significantly strain brake fluid gaskets.
